Abstract
The mounting of an electric enclosure (1) for electric connector and switch embeddable in a piece of masonry work requires the connecting of electric wires (25) to an electrically conductive region or terminal inside the enclosure. The connection requires screwing in the enclosure wires by means of an intermediate part. To facilitate the mounting of these electric enclosures for electrical connectors and switches, the invention provides for the mounting of these enclosures by embedding by simple sliding of a sleeve (3) inside a housing (2) in such a way that the female terminals directly linked to the electric wires of the enclosure are in contact with the male terminals of the sleeve. The electric enclosure is dismantled by simply pulling from the sleeve towards the outside of the enclosure.

An electric contact enclosure comprising:
- a housing provided with a hollow compartment, the housing being embeddable in a hole in a wall,
- a contact sleeve designed to receive plugs of a detachable electric connector, wherein the contact sleeve is slidably embedded inside the compartment of the housing, and wherein the compartment is correspondingly complementarily shaped to accommodate receipt of the contact sleeve,
- wherein the contact sleeve comprises three contact strips and the housing comprises three electrically conductive plates each in direct contact with a corresponding one of a plurality of electrical wires extending into the housing and each in direct contact with a corresponding one of the three conductive plates;
- and
- wherein the compartment comprises three communicating cavities each provided with a partition demarcating a connection space designed to each receive one end of a corresponding one of the electrical wires, separated by a main space designed to receive the contact sleeve, and wherein the contact sleeve comprises, correspondingly with the partitions, three protruding features, and wherein a part of each partition is formed by a corresponding electrically conductive plate.
